[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The purpose of the present invention is to provide a one-item-one-code association system and method, which improves the accuracy of associating single items with box codes through the cooperation of two photoelectric detection components and a processor.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, the present invention provides a one-object-one-code association system, including: a transmission component 1, a first photoelectric detection component 2, a second photoelectric detection component 3 and a processor.

[0041] The conveying component 1 is used to convey items.

[0042] The first photoelectric detection component 2 is provided on the conveying component 1 , and the first photoelectric detection component 2 is used to detect a first photoelectric signal of an object.

[0043] The second photoelectric detection component 3 is provided on the conveying component 1 , and the second photoelectric detection component 3 is used to detect a second photoelectric signal of the object.

[0044] In this embodiment, there is a set distance between the first photoelectric detection component 2 and the second photoelectric detection component 3, and the article passes through the first photoelectric detection component 2 and the second photoelectric detection component 3 in sequence on the conveyor 1. The first photoelectric detection component 2 and the second photoelectric detection component 3 are both photoelectric detection electric eyes.

[0045] As a specific embodiment, the number of the first photoelectric detection eye and the second photoelectric detection eye is two. The two first photoelectric detection eyes are respectively arranged on both sides of the conveying component 1, and the two second photoelectric detection eyes are also respectively arranged on both sides of the conveying component 1 to improve the accuracy of photoelectric detection.

[0046] The processor is connected to the first photoelectric detection component 2 and the second photoelectric detection component 3 respectively. The processor is used to store the standard transmission time, generate the box code of the corresponding item according to the first photoelectric signal, determine the item transmission time according to the first photoelectric signal and the second photoelectric signal, and judge whether the item is moved between the first photoelectric detection component 2 and the second photoelectric detection component 3 according to the standard transmission time and the item transmission time. If the item is moved, the box code corresponding to the item is deleted; otherwise, the box code is associated with the item.

[0047] Specifically, the processor includes: a storage module, a box code generation module, a time determination module, a judgment module, a box code deletion module and an association module.

[0048] The storage module is used to store the standard transmission time.

[0049] The box code generation module is connected to the first photoelectric detection component 2, and is used to generate a box code corresponding to the item according to the generation time of the first photoelectric signal.

[0050] The time determination module is connected to the first photoelectric detection component 2 and the second photoelectric detection component 3 respectively, and is used to determine the object transfer time according to the generation time of the first photoelectric signal and the generation time of the second photoelectric signal.

[0051] The determination module is connected to the storage module and the time determination module, respectively. The determination module is configured to determine whether the object has been removed between the first photoelectric detection component 2 and the second photoelectric detection component 3 based on the standard transfer time and the object transfer time. If the standard transfer time and the object transfer time are equal, the object has not been removed; otherwise, the object has been removed.

[0052] The box code deletion module is connected to the judgment module and the box code generation module respectively, and is used to delete the box code corresponding to the item when the item is removed. Preferably, the box code includes the generation time of the first photoelectric signal and the item information.

[0053] The association module is connected to the judgment module and the box code generation module respectively, and is used for associating the box code with the item when the item has not been removed.

[0054] During the association process, if an item is taken away, the processor will not receive the second photoelectric signal of the object and will automatically clear the box code of this item without recursively affecting the accuracy of subsequent data.

[0055] Furthermore, the one-item-one-code association system further includes a speed detection component. The speed detection component is disposed on the transmission component 1 and is connected to the processor. The speed detection component is configured to detect the transmission speed of the transmission component 1. The processor is further configured to determine a standard transmission time based on the transmission speed and the distance between the first photoelectric detection component 2 and the second photoelectric detection component 3.

[0056] In this embodiment, the speed detection component is a speed encoder 4. As a specific embodiment, the processor can be a computer controller 5 or a PLC (Programmable Logic Controller) 6. The PLC 6 receives pulses fed back from the speed encoder 4 and calculates the number of pulses required between the first photoelectric signal and the second photoelectric signal. The distance between the first and second photoelectric detection eyes is fixed, and the final box code information is determined at the second photoelectric detection eye.

[0057] The speed encoder 4 is connected to the shaft of the transmission component 1. The pulse amount of the speed encoder 4 is fixed. When the shaft rotates, the speed encoder 4 will output pulses, and the PLC6 or counter receives the pulses. Depending on the speed of the shaft rotation, the total amount of pulses received per unit time is also different. The actual transmission speed (m / min) is calculated based on the pulse amount and the actual rotation length.

[0058] Furthermore, it is also possible to determine whether the article is a qualified box by judging whether the pulse of the speed encoder 4 is within a set range, and to remove the unqualified boxes and perform diversion processing.

[0059] In order to better understand the solution of the present invention, the following provides a one-item-one-code association method based on the above-mentioned one-item-one-code association system, such as Figure 2 shown.

[0060] (1) For any article, the article is transported by the transport component 1 .

[0061] (2) When the article passes through the first photoelectric detection component 2, a first photoelectric signal is generated by the first photoelectric detection component 2 and sent to the processor.

[0062] (3) When the processor receives the first photoelectric signal, it generates a box code for the item and starts timing.

[0063] (4) When the article passes through the second photoelectric detection component 3, a second photoelectric signal is generated by the second photoelectric detection component 3 and sent to the processor.

[0064] (5) If the processor does not receive the second photoelectric signal within the standard transmission time, the processor deletes the box code of the item; otherwise, the processor associates the box code with the item.

[0065] Furthermore, the box code is sprayed on the box into which the articles are placed by a printer.

[0066] In addition, the association between box codes and items can be uploaded to the cloud server.

[0067] Each item first passes through the first photoelectric detection eye, generating a first photoelectric signal. The processor generates the corresponding box code based on the first photoelectric signal. When the item passes through the second photoelectric detection eye, a second photoelectric signal is generated. The processor determines whether the item is correct based on the timing of the first and second photoelectric signals. If so, the box code is assigned to the item; otherwise, the box code is deleted. Specifically, a speed encoder measures the transmission speed, and the transmission time is calculated based on the transmission speed and the distance between the two photoelectric detection eyes. If the transmission time is equal to the set time, the item is correct; otherwise, it is incorrect.

[0068] The present invention does not need to record the order of associated items in the computer memory, that is, it will not cause the logical order of items and box codes to be inconsistent and the association relationship to be confused due to random inspections or the removal of abnormal boxes during the transportation of items, thereby improving the accuracy of the association between items and box codes.

[0069] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
